      Given a system administrator has stopped the NetworkManager service, added virtual Ethernet interfaces eth1 and eth1_p, and applied a configuration using nmstatectl,

      When they apply an updated configuration with modified routes using nmstatectl,

      Then, the system should successfully update the routes as defined in the new configuration and the new next-hop addresses should be applied and visible in the routing table.

      Definition of Done:

      • The implementation meets the acceptance criteria
      • Integration tests are written and pass
      • The code is part of a downstream build attached to an errata
